Nonsense. I am an engineer involved in silicon design.
Commercial silicon is normally simulated at 90 degrees C,
20 degrees above the case temp maximum for commercial
silicon ( 70 degrees C)
You want my honest opinion about the non-adjustable 135 degree
limit in the NV35 driver ? Probably a silicon-design screw-up - it was
meant to be lower..... Limit seems to be around 90 degrees C
in the 6800 family, with (according to another thread in this
newsgroup) slowing of the internal clock-rate a la Intel's protection
mechanism on their CPUs.
Military silicon -- based on very conservative processes, 350 nm
or higher --- is only rated to 125 degrees C.
Run your 5900 without a fan ( or equivalently-efficient heat
removal ) at your peril; just make sure that you have money
for a replacement in the bank. The failure mode is normally
catastrophic and irreversible; frequently with no warning.
